Description

Technical Field

[0001] This utility model relates to the field of diaphragm pump technology, specifically a double-layer diaphragm pump structure that improves sealing performance. Background Technology

[0002] Diaphragm pumps, also known as control pumps, change the flow rate of fluid by receiving control signals from the control unit and using power. The role of diaphragm pumps in the control process is to receive control signals from the regulator or computer, change the flow rate of the controlled medium, and maintain the controlled parameters within the required range, thereby achieving automation of the production process.

[0003] Currently, the main body of the diaphragm pump is connected and fixed to the connecting chamber cover with bolts. After replacing the diaphragm, the disassembled main body of the diaphragm pump needs to be reconnected to the connecting chamber cover with bolts. However, since the main body of the diaphragm pump is heavy and is suspended in the air during installation, it requires multiple people to work together, which is quite troublesome. Utility Model Content

[0004] The purpose of this invention is to provide a double-layer diaphragm pump structure that improves sealing performance, thereby solving the problems in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a double-layer diaphragm pump structure for improving sealing performance, comprising an air inlet pipe, a connecting chamber cover, an exhaust pipe, and a diaphragm pump body. Each side of the diaphragm pump body is provided with a connecting chamber cover. The air inlet pipe is connected to the bottom of the two connecting chamber covers, and the exhaust pipe is connected to the top of the two connecting chamber covers. A bracket connecting seat is fixed to the top of the diaphragm pump body, and a bracket is installed on the bracket connecting seat. The top of the bracket hangs on the exhaust pipe.

[0006] Preferably, the hanger consists of a hanger body, a connecting rod, and a connecting block. The hanger body is located at the top of the connecting rod, the connecting block is located at the bottom of the connecting rod, and the hanger connecting seat has a slot that mates with the connecting block.

[0007] Preferably, the main body of the bracket consists of a base plate, arm plates, and hanging plates. An arm plate is fixed to each of the top two sides of the base plate, and the two arm plates are V-shaped. The hanging plates are fixed to the top of the arm plates.

[0008] Preferably, the connecting rod consists of a threaded rod sleeve, a threaded rod, and a nut cap. The lower part of the threaded rod is located inside the threaded rod sleeve, the upper part of the threaded rod is rotatably connected to the base plate, and the nut cap is fixed to the top of the threaded rod.

[0009] Preferably, a positioning sleeve is fixed at the bottom of the main body of the bracket, and the lower part of the positioning sleeve is fitted onto the outer surface of the threaded rod sleeve.

[0010] Compared with the prior art, the beneficial effects of this utility model are: the diaphragm pump body and the exhaust pipe of this utility model are provided with a bracket, which can keep the diaphragm pump body suspended, thereby facilitating the disassembly and assembly operations of the staff. The bracket of this utility model can be detached from the diaphragm pump body, making it more flexible to use; The main body of the bracket of this utility model is composed of a base plate, an arm plate and a hanging plate. Through the V-shaped structural design, the main body of the bracket can avoid the exhaust port of the exhaust pipe, and at the same time, the weight of the diaphragm pump body can be distributed to avoid the weight of the diaphragm pump body being concentrated at a certain position on the exhaust pipe. The connecting rod of this utility model is a length-adjustable structure composed of a threaded rod sleeve, a threaded rod, and a nut cap, so that the bracket can adapt to diaphragm pumps of a certain size range. At the same time, after the exhaust pipe bends, it can be adjusted accordingly so that after the bracket suspends the diaphragm pump body, the bolt holes on the diaphragm pump body are aligned with the bolt holes on the connecting chamber cover. This utility model uses a positioning sleeve to prevent the main body of the hanger from rotating, thus avoiding the situation where the hanging plate on one side cannot fully rest on the hanger after the main body of the hanger rotates. At the same time, the positioning sleeve can also prevent the surface of the threaded rod from getting wet or contaminants, which would cause the surface of the threaded rod to rust too quickly.

[0014] Please see Figure 1-4 In this embodiment of the present invention, a double-layer diaphragm pump structure for improving sealing performance includes an air inlet pipe 1, a connecting chamber cover 2, an exhaust pipe 3, and a diaphragm pump body 5. A connecting chamber cover 2 is provided on each side of the diaphragm pump body 5. The air inlet pipe 1 is connected to the bottom of the two connecting chamber covers 2, and the exhaust pipe 3 is connected to the top of the two connecting chamber covers 2. A bracket connecting seat 6 is fixed to the top of the diaphragm pump body 5, and a bracket 4 is installed on the bracket connecting seat 6. The top of the bracket 4 is hung on the exhaust pipe 3. An additional diaphragm layer is added to the diaphragm inside the diaphragm pump body 5 to improve the sealing performance of the diaphragm pump body 5.

[0015] The bracket 4 consists of a bracket body 7, a connecting rod 11, and a connecting block 12. The bracket body 7 is located at the top of the connecting rod 11, and the connecting block 12 is located at the bottom of the connecting rod 11.

Through the V-shaped structural design, the main body 7 of the hanging frame can avoid the exhaust port of the exhaust pipe 3, and at the same time, the weight of the diaphragm pump body 5 can be distributed to avoid the weight of the diaphragm pump body 5 being concentrated at a certain position on the exhaust pipe 3. The connecting rod 11 of this utility model is a length-adjustable structure composed of a threaded rod sleeve 13, a threaded rod 14 and a nut cap 15, so that the bracket 3 can adapt to diaphragm pumps of a certain size range. At the same time, after the exhaust pipe 3 bends, it can be adjusted accordingly so that after the bracket 3 suspends the diaphragm pump body 5, the bolt holes on the diaphragm pump body 5 are aligned with the bolt holes on the connecting cavity cover 2. The positioning sleeve 16 of this utility model can prevent the main body 7 of the hanger from rotating, thus avoiding the situation where the hanging plate 10 on one side cannot be fully placed on the hanger 3 after the main body 7 of the hanger rotates. At the same time, the positioning sleeve 16 can also prevent the surface of the threaded rod 14 from getting contaminated with water or pollutants, which would cause the surface of the threaded rod 14 to rust too quickly.
